First, _________________ __________________ are produced in two almond-shaped organs known as
the __________________________. During the process of ____________________________, a
mature egg ( ______________) is released and enters one of two _________________
________________. For a few days the egg cell travels towards the pear-shaped
_______________________. The lining of this organ thickens in preparation for a fertilized egg. If the
egg is not fertilized by the male __________________ ___________________, it will leave the body
together with the lining of the uterus and a small amount of blood. This is called
_____________________________. The lower portion of the uterus is called the _________________
and is a common site of cancer in women. The female organ of intercourse is the
_____________________________. A circular fold of skin is usually present at the entrance to this
organ and is called the ________________________. Outside of this organ are folds of skin covered
with pubic hair known as the ______________________. Between these skin folds is a small, round,
sensitive area of skin called the ____________________. The development of the reproductive system
is triggered by the hormones _________________________ and ________________________, which
cause many physical changes in a girl. This period of change is called ___________________________.

reproductive system correct. Each will be used once.
Cowper’s gland
epididymis
erection
orgasm
scrotum
semen
sperm
testes
urine
prostate
seminal vesicle
nocturnal emissions
vas deferens
urethra
penis
First, __________________________ are produced in the small seminiferous tubules of the
___________________. These oval-shaped glands are protected by a sac called they
___________________. After the sperm cells are produced, they are stored in a large coiled tube on the
outer surface of each testicle called the _______________________. From this tube the sperm go into a
larger tube called the ________________________ ________________________, which eventually
carries them to the external male reproductive organ, the ___________________. Along the way sperm is
nourished by a sugary fluid from the _____________________ _________________________, a chemical
fluid from the ___________________________ which is the most common site of cancer in men, and fluid
from the ________________________ _____________________ which are two small glands located near
the bladder. These fluids plus the sperm cells combine to form ____________________, the fluid
ejaculated from the penis during ____________________. Before a male can ejaculate, the spongy tissue
surrounding the penis becomes engorged with blood causing the penis to become stiff and hard. This is
known as an _________________________. The tube that carries the semen from the body is the
________________________. This tube also carries _______________________ from the bladder.
Males can also have uncontrolled ejaculation during sleep, which are called
___________________________ ____________________________.
